Intermediate and long term outcome of patients after device closure of ASD with special reference to complications

Device closure of Secundum atrial septal defect [ASD] is an accepted mode of treatment in selected patients with a suitable defect. The major initial concern over the long term outcome has been erosions and more recently development of aortic regurgitation. Objective was to assess the intermediate and long term outcome of patients with device closure of ASD with special reference to complications. Two hundred and four patients with significant Secundum ASD, 16 months to 55 years [median 8 years] were considered for transcatheter closure with the Amplatzer septal occluder from October 1999 to April 2009 with follow up examinations at 1, 3, 6, and 12 months and thereafter at yearly interval. Device closure of ASD was done successfully in 202/204 patients. The immediate [first 24-hour] major complications included device embolization [n=4], pericardial effusion [n=1] and 2:1 heart block [n=1]. At a mean follow up of 4.9 years [90 days to 9.6 years, median 5.3 years] complete closure was documented in all patients. Two patients [1%] had developed mild aortic regurgitation. A trial fibrillation occurred in 3 adult patients [1.5%] at a mean of 2 weeks post procedure with complete recovery within 6 months. There were no late embolizations, erosions or thromboembolic events on long term follow up. Device closure of secundum ASD using Amplatzer septal occluder is safe and effective in intermediate and long term follow up with extremely low mortality rate. The risk of development of aortic regurgitation or atrial fibrillation is also very low

Single tooth implants, a viable method to replace lost individual teeth

A new surgical and prosthetic procedure is described for replacing a missing single tooth. Eleven patients were treated with Dentsply/Core-Vent titanium implants with Hex-Lock abutments. All had single tooth replaced. With this procedure there has been no need to destroy adjacent teeth by cutting or filing them down. The procedure is a viable method to replace teeth lost due to trauma or failed dental procedures

Dental implantology in Pakistan: report of 34 osseointegrated core-vent implants after 24 months

Osseointegrated implant supported dentures are an accepted method of replacing lost natural teeth. In Pakistan we introduced this technology of Core-Vent implants three years ago. We report on the status of the thirty-four consecutively placed Core-Vent corporation dental implants in six patients. Of the thirty-four placed two failed to integrate. The remaining were able to sustain implant supported dentures in all six of the patients
